Mario Sergio Cubas is due to re‑register on the New York attorney register file of Sep 29, 2026. Admitted in 2020 in the Second Department, with an office in Floral Park, NY; next registration due Oct 2026. Since Jul 3, 2026 it has moved only through the routine two-year cycle.

What this status means on the register

On the register, “Due to re‑register” means the attorney has a biennial registration falling due or overdue: the rule asks for it within 30 days after the attorney’s birthday in each alternate year, and the record gives the month it is due. The value stays until the register records the filing or marks the registration delinquent, so the month can have passed; by itself it is not a finding.

How to confirm it officially

For a statement of Mario Sergio Cubas’s standing, contact the Attorney Registration Unit of the NY Office of Court Administration (nycourts.gov/attorneys), or ask the Appellate Division, Second Department, which admitted Mario Sergio Cubas in 2020. A complaint about this attorney would go to the Second Department’s Grievance Committee for the Tenth Judicial District, which covers Nassau County, where the register places the office.

This page reads the register file of Sep 29, 2026, and the court system’s own search can be newer; the register shows only the current value, so a suspension that ended before the files we hold, or a censure, leaves no trace here (Appellate Division decisions are published through the court system’s Law Reporting Bureau).
